I am confused on how to do this so please help me:
Evaluate:
2[(5+7)+(3-2)-3(2+2)]
PEMDAS

2[(5+7)+(3-2)-3(2+2)]
2(12 + 1) - 3(4)
26 - 12 = 14
Thank you very much :)
God bless you and have a nice day!
You're very welcome.
To evaluate the given expression, you need to follow the order of operations, which is also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). Here's a step-by-step guide to help you evaluate the expression:
Step 1: Simplify within the parentheses:
- Inside the first parentheses: (5 + 7) = 12
- Inside the second parentheses: (3 - 2) = 1
- Inside the third parentheses: (2 + 2) = 4
The expression now becomes: 2[12 + 1 - 3(4)]
Step 2: Simplify any multiplication or division:
- Multiply 3 by 4: 3 * 4 = 12
The expression now becomes: 2[12 + 1 - 12]
Step 3: Perform addition and subtraction from left to right:
- Add 12 and 1: 12 + 1 = 13
- Subtract 12 from 13: 13 - 12 = 1
The expression now becomes: 2[1 - 12]
Step 4: Perform any remaining calculations:
- Subtract 12 from 1: 1 - 12 = -11
The final answer is: -11
Therefore, the evaluated value of the given expression is -11.
